Abstract (en)
[origin: WO2018028779A1] The invention relates to an encoder for encoding a vector comprising channel state information and/or a pilot sequence, the encoder comprising a determining unit configured to determine a cell of a sphere mesh, wherein the cell includes the vector, a mesh refinement unit configured to determine a refined sphere mesh based on an initial sphere mesh, and a representation unit configured to determine a binary representation of a first identifier of an initial cell of the initial sphere mesh that includes the vector and a second identifier of a refined cell of the refined sphere mesh that includes the vector.
